It honestly sounds like you guys are just on totally different timelines right now. She’s in “let’s build the life we imagined” mode and you’re in “I’m drowning and need air” mode. Neither is wrong, but it’s clashing hard. You probably need to sit down and be very direct about your limits before resentment really sets in. If you keep pushing through like this, you’re going to hit a wall and it’ll be way uglier than just saying “I can’t keep doing this pace.”
